BACKGROUND

Biomarkers are molecular indicators of a specific biological property, abiochemical feature or facet that can be used to measure the progress ofa disease or the effects of a treatment. For example, serum low-densitylipoprotein (LDL) is a biomarker of cholesterol and blood pressure,while the P53 gene is a biomarker for cancer. For chronic diseases andconditions, such as diabetes and allergies, accurate diagnosis isparticularly important, especially where the side effects of a treatmentare severe.

Diagnostic tests using biomarkers as molecular indicators not onlydetect the presence or absence of the biomarker, but often must measurethe exact concentration of a biomarker to determine whether an abnormalcondition exists. Because of the requirement for accuracy, the processof sample collection, preparation, and analysis are often complicatedand time consuming. Currently, blood-based assays for biomarker presenceor activity are considered to be the “gold standard” for biomarker-typeassays.

Despite the desire for accurate results, rapid, point of care analysisof biological samples using biomarkers is becoming increasinglyimportant in the present medical environment due to the need for quickresults.

DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles of thepresent disclosure, reference will now be made to the embodimentsillustrated in the drawings, and specific language will be used todescribe the same. It will nevertheless be understood that no limitationof the scope of this disclosure is thereby intended.

The disclosure of the present application provides various compositions,systems, and methods for biomarker stabilization and analysis.Specifically, formulations are disclosed herein, which function topreserve the level of diagnostic markers, such as biomarkers, in bodyfluids, from enzymatic alteration, or degradation. Additionally, methodsfor the collection and analysis of body fluids are disclosed. Themethods and formulations disclosed herein can be used to improve thesampling and testing of a body fluid by conditioning the body fluids forthe stabilization of specific biomolecules and/or drug metabolites. Asused herein, the term “body fluids” includes fluids produced by thebody, such as saliva, or fractions thereof, mucous secretions, tears,sweat, bile, semen, urine, vaginal secretions, exhalations, analsecretions, blood, plasma, serum and mixtures of thereof. Body fluidsmay also comprise cancer cells, peripheral blood mononuclear cells,lymphocytes, lymph fluid, and other tissue secretions or fluid.

Saliva

Saliva is clear, viscous fluid with a slightly alkaline pH and a pIrange from 11.5-3.0. It is hypotonic, composed of about 99.5% water, andalso contains ions (e.g., K⁺, Na⁺, Ca²⁺, Mg²⁺, H⁺, Cl⁻, HCO₃ ⁻, I⁻, F⁻,HPO₄ ²⁻), and small organic molecules (e.g., ureas, hormones, lipids,DNA, and RNA). There are multiple contributors to the composition ofsaliva. Saliva has a complex “proteome”—10⁶ D glycoproteins to 1000Dpeptides. It contains secretory products of salivary glands, products ofB cells, PMNs, epithelial cells, and bacteria. Major (e.g., parotid,submandibular, and sublingual) and minor (e.g., palatine and retromolar)glands contribute to the composition of saliva, along with extraneouscontributors such as gingival crevicular fluid, serum proteins, whiteblood cells and their byproducts, oral epithelial cells, oral bacteria,food debris and dissolved food components.

Saliva from different glands may differ in composition. For example,saliva from the parotid gland is dominated by serous secretory cells,whereas saliva from the submandibular and sublingual glands and minorglands are mixed serous or mostly mucous. There can also be qualitativeand quantitative differences in saliva output that affect itscomposition. Glandular contribution to saliva is affected by level ofgland activity. The amount of saliva secreted per minute or the salivaryflow rate influences the concentration of the constituents as well asthe proportion of the constituents from each of the three pairs of majorsalivary glands and the minor salivary glands.

I. Stabilizing Agents

According to at least one embodiment of the present disclosure,conditioning of body fluids for the preservation of diagnostic markersmay be accomplished through the use of stabilizing agents, which may beincorporated into one or more carrier vehicles, such as rinses, gums,beverages, and confectionaries. For example, specific rinses and/orpre-rinses specially formulated according to the specific molecule ormolecules (the diagnostic marker) to be detected in the body fluid, maycontain a stabilization agent. The use of rinses and pre-rinses of thepresent disclosure to condition the body fluid may enhance thesensitivity for detection of specific diagnostic markers for clinicaldiagnosis. Additionally, this process may improve the signal-to-noiseratio for a better diagnostic yield. Further, each rinse/pre-rinse canbe specifically formulated to reduce or prevent false positive and falsenegative results.

In at least one embodiment of a stabilizing agent of the presentdisclosure, the stabilizing agent may act to prevent/decrease thedegradation, or reduction of activity, of diagnostic markers. In atleast one embodiment, the stabilizing agent may be comprised of one ormore Generally Regarded as Safe (GRAS) compound, as determined by theFood and Drug Administration of the United States of America, such asthose listed in Table I. An exemplary embodiment of a stabilizationagent may act to stabilize a diagnostic marker, and/or to bind to adestructive component to prevent the destructive component fromdegrading or decreasing the activity of the diagnostic marker.

In additional exemplary embodiments of the stabilization agent, thestabilizing agent may comprise at least 2, at least 3, at least 4, atleast 5, at least 6, at least 7, at least 8, at least 9, at least 10, atleast 15, at least 20, or at least 25 compounds which acts to stabilizethe diagnostic marker, and/or to bind to a destructive component toprevent the destructive component from degrading or decreasing theactivity of the diagnostic marker. Further, in various embodiments thestabilizing agent of the present disclosure may be present in at a levelof between about 200 ppm to about 2,000 ppm, about 400 ppm to about 1600ppm, about 600 ppm to about 1400 ppm, about 800 ppm to about 1200 ppm.Moreover, in at least one embodiment, the stabilizing agent may bepresent at a level of approximately 500 ppm.

According to at least one exemplary embodiment, the stabilizing agentmay block at least one enzymatic activity of a destructive component.The destructive component may be one or more component of a bodily fluidwhich acts to degrade, or decrease the activity of a diagnostic marker.Further, the destructive component may be one or more Amylases,Lysozymes, Peroxidases, Glycosidases, Esterases, Proteases, and/orPeptidases. In an exemplary embodiment, the stabilizing agent may be anaturally occurring or artificial protease inhibitor, DNase inhibitor,or RNase inhibitor. Specifically, a natural stabilizing agent mayinclude any component found from food products (including, but notlimited to, the Solanaceae family), herbs, or spices that acts todecrease the effect of a destructive component. For example, exemplaryembodiments of the natural stabilizing agents may be any of theinhibitors found in lima beans, soybeans, or avian eggs (such asovomucoid glycoprotein protease inhibitors) (See Table II). Moreover, anembodiment of the stabilizing agent may also comprise a molecule whichspecifically inhibits the activity of a molecule which targets thediagnostic marker for degradation or inactivation. Further, thestabilizing agent may act to alter the composition of the body fluid(such as pH, or ion concentration) to decrease the degradation orinactivation of the diagnostic marker.

C. Exemplary Targets for Stabilizin Agent(s)

1. Amylase

Amylase is an enzyme that breaks down starch into sugar, and is found insuch places as human saliva, where it begins the chemical process ofdigestion. The α-amylases are calciummetalloenzymes that are completelyunable to function in the absence of calcium. Through acting at randomlocations on the starch chain, α-amylase breaks down carbohydrates intomaltotriose and maltose from amylase. In animals, α-amylase is a majordigestive enzyme that has an optimum pH of 6.7 to 7.0.

In at least one embodiment of a stabilizing agent of the presentdisclosure, the stabilizing agent may be an inhibitor of α-amylase.Further, the stabilizing agent may be active in a biological fluid, suchas in saliva. In an exemplary embodiment, a stabilizing agent maycomprise one or more of Fixanal® Buffer 6.0 (Sigma-Aldrich Co.),aluminum sulfate hydrate, aluminum hydroxide, bentonite, and aluminumpotassium sulfate dodecahydrate.

Further, the rinse in anexemplary embodiment of a method 700 of the present disclosure, may beingested to stabilize a diagnostic marker present in the bodily fluid,such as in urine, semen, anal secretions, and vaginal secretions.

The step 702 of mixing a body fluid with a carrier may occur prior to,or after isolation step 708 of the body fluid. As an exemplaryembodiment, a rinse may be used to rinse the mouth. Afterwards, therinse containing the treated body fluid may be collected by spitting,suction, or other means. Alternately, expirated saliva may be mixed witha rinse to treat the saliva ex vivo.
